Papaji, also known as H.W.L. Poonja, was a renowned Advaita Vedanta teacher who dedicated his life to guiding others towards enlightenment. His teachings revolved around the concept of self-realization and the ultimate goal of attaining enlightenment.

Papaji's teachings emphasized the importance of self-inquiry and introspection as the means to attain enlightenment. He believed that the true nature of the self is pure consciousness, and that the key to realizing this is through self-inquiry. This process involves questioning the nature of one's own existence and ultimately realizing that the self is not separate from the universal consciousness.

Papaji also stressed the importance of surrender and letting go of the ego in order to attain enlightenment. He taught that the ego, or the sense of a separate self, is the root cause of suffering and that true liberation can only be achieved by transcending it. He encouraged his students to surrender to the present moment and to trust in the divine will, rather than trying to control or manipulate their experiences.

One of Papaji's most famous teachings was the "Who am I?" inquiry, which he learned from his own teacher, Sri Ramana Maharshi. This simple yet profound question encourages individuals to look within and question their own identity, ultimately leading to the realization that the self is not limited to the body or the mind, but is the infinite consciousness that pervades everything.

Papaji also emphasized the importance of living in the present moment and letting go of attachments to the past and future. He believed that enlightenment can only be experienced in the present moment and that the mind's constant dwelling on the past or future only creates suffering.

In addition to his teachings, Papaji was known for his compassionate and loving nature. He encouraged his students to approach their spiritual journey with a sense of joy and playfulness, rather than seriousness and rigidity. He believed that enlightenment is not a serious or distant goal, but rather a natural state that can be experienced in every moment.

In conclusion, Papaji's teachings on enlightenment revolved around the concepts of self-inquiry, surrender, living in the present moment, and approaching the spiritual journey with a sense of joy and playfulness. His teachings continue to inspire and guide people on their quest for self-realization and enlightenment.
